To adjust a Rain Bird sprinkler head, the process depends on the type of sprinkler head you have (rotor, spray head, rotary nozzle, or impact sprinkler). Here are the general steps for the most common types:

Adjusting a Rain Bird Rotor Sprinkler Head

  1. Set the Fixed Left Edge:
    • Pull up the sprinkler head slightly.
    • Turn the center cap (turret) all the way to the right until it stops.
    • Then turn it all the way to the left until it stops.
    • Rotate the entire rotor case to align the left edge with where you want the water to start spraying. This left edge is fixed and cannot be adjusted beyond these stops
  1. Adjust the Arc (Spray Angle):
    • Insert a flathead screwdriver or Rain Bird adjustment tool into the arc adjustment screw on top of the sprinkler.
    • Turn clockwise (+) to increase the arc (wider spray).
    • Turn counterclockwise (-) to decrease the arc (narrower spray).
    • The arc can be set between 40 degrees and 360 degrees.
    • Do this adjustment while the sprinkler is running and only turn the screw in the direction the rotor is turning to avoid stripping gears
  1. Adjust the Spray Distance (Radius):
    • Insert a flathead screwdriver into the radius adjustment screw, usually located inside a small opening on the head.
    • Turn clockwise to reduce the spray distance (up to about 25% reduction).
    • Turn counterclockwise to increase the distance.
    • Avoid unscrewing too far to prevent the nozzle from loosening

Adjusting a Rain Bird Spray Head

  • Pull up the spray head stem gently.
  • Tighten the nozzle clockwise to secure it.
  • Turn the colored top ring clockwise to increase the arc or counterclockwise to decrease it.
  • Use the black bottom dial to adjust spray distance: turn clockwise to increase distance, counterclockwise to decrease it

Adjusting a Rain Bird Impact Sprinkler

  • Lift the internal assembly out with a flathead screwdriver.
  • Adjust the metal stops on the collar to set the right and left spray positions (arc).
  • Push the trip pin up for a full 360-degree rotation.
  • Turn the top nozzle clockwise to decrease distance, counterclockwise to increase.
  • Use the diffuser pin to reduce spray distance up to 25%

Additional Tips

  • Avoid using wrenches on stems to prevent damage.
  • Use rubber gloves for better grip on wet heads.
  • Inspect heads annually for leaks, clogs, or damage to maintain efficiency

These adjustments help ensure even lawn coverage, prevent watering sidewalks or driveways, save water, and keep your system efficient
